Hi Venkata Balaji,
Thank you!
Yes, streaming replication cannot be setup between two different versions. That is true.
I am looking to upgrade both primary and standby with minimal outage to application….. I want to know if it is possible. If it is not possible, is there any architecture where we can minimize upgrade related outage?
In my previous email, i suggested/asked the possibility of using Slony replication in your environment. It depends on lot of factors (database size, number of tables, pl/pgsql code etc..) though. Please let us know your thoughts on this. We can probably move further on this discussion.
